' columns on msnc I UNIT D SiA Es Be it linown that I, JOSEPH A.GREER,01 the city and county of Galveston, and State of Texas, haveinvented certain new and useful 5 Compounds for the Manufacture ofArtificial Stone;. and I do hereby declare the following to be at full,clear, and exactdescription of the invention, such as will enable othersskilled in X- t'hc'snmo.

This'ini'ention relates to that class of coinpounds used in themanufacture of artificial 'sione; and it consists in composition formedby mixing certain materials in solution and treating them infiirthersolutions, as follows: Take one hundred (li)-'pohnds of, h*druulic l t. four hundred (4H0) pounds of sharp twenty poundsot"po\rdcrct'l 'ma 'nesinn limestone, one (1) pound of powderedzd'chnrcml. one (i pound of black oxide of man- 'illlth'flhen mix thesethoropglily liy pass;
